Ecdysone + Oxygen → 3-Dehydroecdysone + Hydrogen peroxide
Ecdysone + NADPH + Oxygen → Crustecdysone + NADP + Water
3-Dehydro-2-deoxyecdysone → 3-Dehydroecdysone
2,22-Dideoxy-3-dehydroecdysone → 3-Dehydro-2-deoxyecdysone
Diketol ? 2,22-Dideoxy-3-dehydroecdysone
Crustecdysone → 20,26-Dihydroxyecdysone
Cholesterol + Hydrogen Ion + NADH + Oxygen → 7-Dehydrocholesterol + NAD + 2 Water
